LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 729,303, dated May-26,1903. Application filed July 2, 1902. Serial No. 114,104. (No model.)

To aZZ whom it may concern.-

Be it known that I, LEONARD ERIKSON, a citizen of the United States,residing atMalden, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inLighting Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to lighting devices specially adaptedfor use inconnection with the show-cases used in stores; and it consists in thenovel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure 1 is a front view of the lighting device. 'Fig.2 is a cross-sec tion taken on the line or a; in Fig. 1. Fig. 3 is across-section taken on the line y y in Fig. 1. Fig. 4 is a detail rearview of the insulating-block.

A is a trough-shaped reflector of polished metal having a tubular bead bat its lower edge.

B represents brackets for securing the reflector inside the show-case.Each bracket has a lug c, which is attached to the showcase by screws,and a hook d, which engages with the tube 1).

O is a curved arm which is pivoted to the.

upper end of the bracketB and provided with a series of notches e in itssides. The reflector has a hole f in its back, which has a narrow slot fon its lower side. The arm 0 is slid through the hole f, and its notchesare placed in engagement with the slot f. In this manner the reflectoris supported from the brackets B, and its position can be adjusted fromtime to time to throw the light to the best advantage inside theshow-case.

D is a block of insulating material secured at the middle part of thereflector.

E represents two incandescent electric lamps of any approved manufacturesecured to the block D and projecting from it in opposite directionsinside the trough of the reflector. i

The block D has two recesses g and 7?. at its middle part, and g andhare two metallic bridge-pieces arranged in these recesses, respectively.Thebridge-piecegisarranged on the axis of the lamps and isconnected totheir central terminals. The bridge-piece 7b is arranged to one side ofthe axis of the lamps and is connected to their other terminals. Theline-wires '1; and i are passed up the tube 1) and are connected to thebridge-pieces g and h, respectively, by binding-screws.

The two recesses g and 77. have a shallow recessj formed in the block Daround them,

- andj' is a curved plate of insulating material arranged in the recessj between the bridgepieces and the metallic'reflector. The block D has alongitudinal groove is along its lower edge, which engages with thefront part of the tube 19. The block is held in position by this grooveit and a screw it, which engages with a hole in the upper edge-of thereflector and a hole in the said block.

WhatI claim is 1.-'The combination, with a trough-shaped reflectorhaving a tube at one edge and holes and slots in its rear part, of oneormore lamps arranged inside the reflector, supportingbraekets havinghooks which engage with the said tube, and arms pivoted to the saidbrackets and provided with "notches for engaging with the said slots,substantially as set forth.

2. The combination, with a trough-shaped reflector having a tubeat oneedge, of ablock LEONARD -ERIKSON. Witnesses:
